摘要

Based on the comprehensive analysis about the hydrogeological condition, ecological environment, and the characteristics of geological environment, energy is devoted to constructing a function evaluation indicator system of shallow groundwater with Jinjiang regional characteristic in the light of the assessment indicator system proposed in technical requirement for function evaluation and zoning of shallow groundwater issued by ministry of Land and resources. By dint of expert's knowledge and experience, efforts are spent in assigning different weight values to the indicators, classifying function evaluation grading standards, and putting forward a secondary function zoning rating system. Besides, focus is put on building a comprehensive function evaluation model of shallow groundwater by means of analytic hierarchy process based on the constructed assessment indicator system of shallow groundwater. In order to guarantee assessment accuracy, the studied region is split into regular discrete grid for the purpose of calculating the comprehensive assessment index of grid unit. Meanwhile, based on GIS' spatial analysis function, a research is conducted on the overall function zoning map of the shallow groundwater in the studied region to accurately reveal its spatial distribution and exploitation and provide scientific basis for groundwater management.
